Foundation for the PySide6 + pyqtgraph Windows GUI, shared with the terminal
tool. Pure data/IO -- no Qt, no curses.
obdcore/
link.py ElmLink -- ELM327 serial (Mode-01/22, ATRV, DTC read/clear)
mock.py MockLink -- synthetic crank for tests + GUI dev (no truck)
registry.py PidRegistry (verified Ford 6.0 PIDs + confidence) + DtcDatabase
scheduler.py PollScheduler -- prioritized round-robin polling, dead-PID park,
derived channels; tick() is fake-clock test-drivable
store.py TimeSeriesStore (ring buffers + min/max) + CsvRecorder/replay
Design centers on the ELM327 bandwidth limit (~7-15 reads/sec): the active
view subscribes PIDs at chosen rates; acquisition runs off the UI thread;
the GUI only reads the store. FICM_M (09D0) promoted to verified after the
2026-06-30 on-truck crank read (48.0V, intermittent).
tests/test_obdcore.py: decoders vs real truck bytes, crank ramp + peak,
derived BOOST, dead-PID park/revive, record/replay roundtrip -- all pass.
ARCHITECTURE.md: layers, data model, GUI plan, 6.0 stock-PID limits
(no EGT/oil-PSI), feature backlog, P0-P5 roadmap.
